Potassium iodide (KI) tablets

There are two nuclear generating stations in Durham Region. One is the Pickering Nuclear Generating Station. The other is the Darlington Nuclear Generating Station.

In the highly unlikely event of an accident at one of the stations, radioactive iodide may be released into the air. If that happens, potassium iodide (KI) tablets can keep you and your family safe.

Learn more about emergency preparedness.

Who needs KI tablets?

Watch our public health inspectors discuss who is eligible to receive KI tablets.

If you live or work within 10 kilometres of a station, you need to have a supply of KI tablets. Anyone living within 50 kilometres of a nuclear generating station is eligible to receive KI tablets if they want to keep a supply on hand.

Visit preparetobesafe.ca and enter your postal code to find out if you are located within the eligible zone to receive KI tablets.

How does KI work and how many tablets do I need?

This fact sheet answers these questions and many more.

How to order KI tablets

The best way for most residents and businesses to order potassium iodide (KI) tablets is directly from the preparetobesafe.ca website.

If you need assistance in ordering your tablets, call the Durham Health Connection Line at 905-668-2020 or 1-800-841-2729 to speak with a public health inspector.

Getting KI tablets from a pharmacy

Five local pharmacies have partnered with the Health Department and have a limited supply of KI tablets for residents located within 10 kilometres of either the Pickering or Darlington nuclear generating station. Residents can pick up their supply of KI tablets from one of the pharmacies below.

Background information

In 1992, Ontario's Environmental Assessment Advisory Committee held public meetings regarding the suggested expansion of the Ajax Water Supply Plant and recommended that the Durham Nuclear Health Committee (DNHC) be established. After a full consultation with key stakeholders, Durham Regional Council created the DNHC in late 1995.
